We're closing in on the start of spring practice at Georgia, so this week we will take a look at five position battles worth watching this spring.

Yesterday we examined the competition at safety. Today let's move to the defensive line, which lost a starter in Garrison Smith, but should otherwise have plentiful depth and experience:

Ray Drew will be among those tasked with getting a better pass rush for Georgia in 2014.

Returning starters: A number of defensive linemen earned starts for the first times in their careers last fall. Defensive end Sterling Bailey (34 tackles, one sack, one tackle for a loss) started the first eight games and came off the bench for the remaining five. Position mate Ray Drew (43 tackles, six sacks, eight TFLs) started seven times, but never started more than two games in a row at any point. And noseguard Chris Mayes (31 tackles, one sack, one TFL) started to come into his own during his streak of seven straight starts to conclude the season.

Departures: Smith (63 tackles, six sacks, 10 TFLs) started all 13 games last season and was one of the emotional leaders on the defense, earning defensive team captain honors after the season.

Returning reserves:John Taylor (nine tackles, one sack, 1.5 TFLs) and Toby Johnson (seven tackles, 1.5 TFLs) are probably the first names to mention here. Both players appeared in 10 games off the bench in 2013 and should compete for extended playing time this fall. Taylor was a redshirt freshman and still looked a bit green last season, while Johnson was only nine months removed from a season-ending ACL tear when the Bulldogs opened preseason camp a year ago. Josh Dawson (eight tackles, one TFL) appeared in 12 games and started once at end and Mike Thornton (five tackles, one sack, one TFL) appeared in 11 games. Smith mentioned Thornton as a player who might fill a larger role in the Bulldogs' retooled 3-4 scheme under new defensive coordinator Jeremy Pruitt.

Newcomers: Redshirt freshman John Atkins is among the more intriguing players who will enter the mix this spring. He's big and quick enough to play any position along the line, and it wouldn't be a big surprise to see him figure into the line rotation early next season. Noseguard DeAndre Johnson is also coming off a redshirt, but he faces steep competition in the middle this spring. The Bulldogs also signed defensive tackle Lamont Gaillard -- ESPN's No. 55 overall prospect and No. 4 DT -- and ESPN 300 defensive end Keyon Brown, but neither player is on campus yet.

What to watch: The line came into 2013 with limited experience, but ranked among the pleasant surprises for a defense that disappointed overall. The Bulldogs defended the run fairly well -- Georgia's average of 3.7 yards allowed per carry ranked second in the SEC -- thanks in large part to typically stout play by the line. With six sacks apiece, Drew and Smith both ranked among the SEC's top pass-rushers, but the group generally struggled to generate a consistent pass rush or convert sack opportunities. Identifying strong rush men will likely rank among new line coach Tracy Rocker's goals for the spring, as will simply teaching his new players how he wants things done. This will be the third line coach in as many seasons for the Bulldogs, so the group has certainly become accustomed to change. It will be a big spring for all of the linemen since Rocker brings a fresh set of eyes to the table, without having formed an opinion based on their performances in previous seasons. It might provide a chance for someone like Johnson -- we recently discussed his situation here -- Taylor or Atkins to grab a bigger role than he previously enjoyed.
